Description

Technical Field

[0001] The present application relates to the technical field of popular science teaching tools, and in particular to a crankshaft mechanism display device for simulating a race. Background Art

[0002] The crank-connecting rod mechanism and the crank mechanism are both important transmission mechanisms, which are used in many mechanical equipment. Their function is to convert circular motion into linear motion, or to convert linear motion into circular motion. As a basic transmission mechanism in the field of mechanics, it is required to be studied in the mechanical majors of various universities, and teachers have also developed various teaching aids to vividly and objectively show the principles and actions to students.

[0003] However, the above-mentioned teaching aids are all for adults, and the teaching objects are college or undergraduate students. They have strong teaching attributes and cannot be used for popular science for children. It is not convenient for children to connect, compare and understand with their daily life, so that they can understand the role and use of the crank-connecting rod mechanism more vividly. Therefore, the teaching and popular science effects are not good. Utility Model Content

[0004] The purpose of the present application is to provide a crankshaft mechanism display device for simulating a race for popular science education for children, which is targeted at children's cognition, connects real life with popular science education, and more vividly displays the principles and uses of the crank-connecting rod mechanism, thereby improving the effects of popular science education and teaching.

[0007] Through the above technical scheme, the cartoon model and the race are combined to simulate the racing and chasing situations of people in life. The crankshaft rotates, thereby driving the movement of multiple connecting rods located on the crankshaft journal, further pushing the slider to move in the slide groove, and realizing the movement of the cartoon model. Due to the different orientations of the journals, the movement trajectory of each slider is different, and the position of the cartoon model is also different, so that the situation of the cartoon model chasing and racing on the fixed plate can be simulated, thereby improving the teaching effect, and the cartoon characters can attract the attention of children. Racing is a common scene in life, which is convenient for children to connect and compare with the scenes in their daily life. When seeing the scene in subsequent daily life, they can repeatedly strengthen the memory of the crank-connecting rod mechanism and understand the principle therein.

[0009] In some embodiments of the present application, the vertical plate includes a side plate and a middle plate, a limiting block is set on one side of the side plate, and limiting blocks are set on both sides of the middle plate. The limiting blocks are set on both sides of the middle plate, which can limit the sliding blocks in the two sliding grooves at the same time.

[0010] In some embodiments of the present application, the cartoon model and the slider are connected in a detachable manner, and the cartoon model and the slider are connected in a detachable manner. The cartoon model that the children like can be replaced as needed to improve the teaching effect and deepen the memory.

[0011] In some embodiments of the present application, there are two sliders, and the cartoon models on the two sliders are mice and cheese, respectively. By simulating the situation of mice chasing cheese, the teaching aids are more vivid and improve the teaching effect.

[0012] In some embodiments of the present application, a driving handle is connected to one end of the crankshaft. The crankshaft is driven by rotating the handle. The teacher can freely adjust the speed and explain the principle while turning the handle to enhance the teaching effect.

[0013] Compared with the prior art, the embodiments of the present application have at least the following advantages or beneficial effects:

[0014] First, cartoon models and racing are combined to simulate a mouse chasing cheese, so as to explain the knowledge of crankshaft and crank-connecting rod mechanism to children. Cartoon models can better attract children's attention. Racing and chasing are common scenes in life, which is convenient for children to connect and compare with scenes in their daily life. When they see this scene in their daily life, they can repeatedly strengthen their memory of crank-connecting rod mechanism and understand the principle behind it.

[0015] Secondly, the cartoon model and the slider are connected in a detachable manner, and the cartoon model that children like can be replaced as needed to improve the teaching effect and deepen the memory. BRIEF DESCRIPTION OF THE DRAWINGS
